These cameras have a simple optical viewfinder, which allows fast framing of a shot.
This burst mode lets users do a number of different things, including grabbing the best frame of a shot, composing an action series, or even changing focus after the shot was taken, Lytro-style.
Each GIF latches onto a central aspect of the clothing or the framing of a shot and extrapolates an absurd extreme, changing the way we look at the original work itself.
For all frames within a shot, the average of those medians was taken.
And Mr. Escoffier paints the frame expressively: a shot of a fire-ravaged apartment takes on a ruined gorgeousness.
The key-frame extraction method is based on a rate-distortion trade-off expressed by a Lagrangian cost function, cost(Shot k ) =Distortion(Shot k ) + λRate(Shot k ) where Rate is the number of key-frames in a shot and Distortion is the Euclidean distance between feature vectors.
"P.R. would fire off hundreds of frames of the same shot, of a smiling Joe handing a Transformer toy to a beaming Iraqi kid," he writes.
The latter was caused by: (a) the need to process all frames of every shot, and (b) the need to calculate higher-order statistics from them and compute additional features.
"Can you go back?" She had her iPhone out and was straining to properly frame a shot of the glowing, plastic-sheeted skeleton of a building.
This choice alleviates both the need for processing all frames of each shot and the need for computationally expensive statistical and other features calculations.
